##### GM1 UAM.POL.VCA.120 Take-off *ED Decision 2025/010/R* **TAKE-OFF PROCEDURES** (a) The take-off procedures define take-off profiles and scheduled data for various environmental conditions and masses. Associated with such profiles and conditions are the minimum operating surfaces, take-off distances and climb performance distances; these are provided (usually in graphic form) with the take-off mass and the take-off decision point (TDP). (b) The minimum dimensions of the take-off surface should be compatible with the chosen take-off procedure. For example, for a vertical take-off (VTO) procedure, the minimum FATO dimensions should be 1.5 D, while for a forward take-off procedure, the minimum FATO dimensions should be the length of the rejected take-off distance required (RTODRV). (c) The landing surface and the height of the TDP are directly related to the ability of the VCA to reject the take-off and land on the surface, following a CFP event before or at TDP. Following a CFP event at or after the TDP, a CMP should exist to perform a continued take-off (CTO) which provides obstacle clearance and distance to reach a point from where climb performance in the first and subsequent segments is assured. The operator should be aware that if the TDP is lower than the top of the vertical segment, it is possible that the rejected take-off (RTO) cannot be performed safely from a given height upwards while meeting the CMP following a CFP. If the RTO is not a foreseen option, then the TDP may be set at the bottom of the vertical segment. Where the TDP is shifted upwards, it will not affect the shape of the continued take-off profile but will shift the min-dip upwards by the same amount that the revised TDP has been increased — with respect to the basic TDP. Such assertions are concerned only with the vertical or the backup procedures and can be regarded as achievable under the following circumstances: — when the take-off procedure is flown, it is based upon a profile contained in the AFM — with the exception of the necessity to perform an RTO; — the TDP, if shifted upwards (or upwards and backward in the backup procedure), will be the height at which performance is available to perform CTO following a CFP; and — if obstacles are permitted in the backup area, they should continue to be permitted with a revised TDP.
